Here is a thought:
Let free enterprise take care of the situation. Someone build a university that only allows homeschooled children to attend. I bet it would have some of the highest rated students in the whole USA.
You know Chewy, I've just recently become aware of Patrick Henry College, which was founded by one of the top dogs in the Home School Legal Defense Association (HSLDA). I think their emphasis is in government and law. Their enrollment is about 95% homeschooled students.
The SAT scores of those in the university is about where the Ivy Leagues are. I wish I could remember more about the article, which was in the most recent HSLDA newsletter, but our son is still too young to be thinking about college as anything other than a future eventuality... specifics to be determined.
For the record, the HSLDA publications are all extremely good.
